摘要：
A preformed oxime-carbapalladacycle complex covalently anchored onto mercaptopropyl modified silica is highly active ( > 99%) for the Suzuki reaction of p-chloroacetophenone and phenylboronic acid in water; no leaching occurs and the same catalyst sample was reused eight times without decreased activity.
